Feds Investigate Arizona Sheriff Paul Babeu's Top Deputy

Federal investigators are looking into whether the No. 2 man in Arizona Sheriff Paul Babeu's office broke the law by politicking while on duty, according to the Arizona Republic.

Since November, Chief Deputy Steve Henry has been exploring the possibility of running for the sheriff's seat because his boss plans to leave the office at the end of the year. Babeu is running for Congress, hoping to turn his national profile as a conservative border hawk into a role in the federal government.

The investigation, being conducted by the US Office of Special Counsel, has been going on since December and does not appear to be related to the sex scandal that Babeu has been facing since last week, the newspaper reported.
